Uni Glo Thread – Funky Fly Tying

UNI Product’s Glo Thread will glow in the dark. Glo Thread feature brighter and longer-lasting phosphorescence.

Phosphorescence and fluorescence are often confused. Phosphorescent materials emit light in total darkness, often for a considerable length of time. Fluorescent materials emit light (in addition to reflecting light like ordinary materials) only in the presence of light. The phosphorescent pigment in UNI Glo products absorbs light from any light source available (a camera flash is a favored source) and releases light or glows in darkness or very low light levels. The glow will last in excess of three hours in total darkness.
